318/360 Crank/347 running on Dyno

usually if you step away from normal you take a bit of heat.
Kudos to the builder!
...3.90 x 3.62 has been good enough for the Corvette for many years!
Didn't see anyone give the OP any "heat" He built a nice motor for sure. And it don't go in a corvette, and in fact, a 350 has been good for a corvette for a lot of years too, don't mean we want one though!
